The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and de- .scribed.

The accompanying -.drawings, referred to herein and constituting .a part hereof, illus- .tra-te one embodimentof .the invention, and

together withthe description, serve'to explain the princ ples of the invention.

Fig. 5 is a side elevation of the delivery mechanism'of a rotary newspaper press with certain of the mechanism'of theinvention applied-thereto, and showing certain mechanism which 'is also shown at the lower right hand part of Fig 2.

In the delivery-mechanism ofrotary newspaper presses it is customary to have the mechanism designate or mark 'roupsconsisting of a predetermined number .of'newspapers in the delivered stack or row, the

-. designation being usually by displacing the Serial N 0. 138,822.

last paperof thedesired number in the continuous row or stack upon thedelivery belt. The present invention is direct-ed to pr0- viding means for nicely usting the flipper,

forming a part of the designating or marking. mechanism, whether or not the numbers of newspapers in the groups are varied or changed.

The present invention is also directed to providing means for varying the operation or.

ieriodicit' of the desi natin or :markin mechanism so as .to indicate or mark groups of different numbers of newspapers as may be desired, and to provide for consequent and concomitant changes or variations in the operation of the various cooperating mecha nism.

The usual construction for such a mechanism comprises in conjunction with the rotary fiy ofthe folder, which lays the complet- 7 ed or folded newspapers in an even row or stack on the-delivery belt, a fiipperor'swinging finger, operating in a definite time relation withthefiy, and which periodically lifts or displaces :a paper'as it is delivered from the fly onto the belt so that itwillproject above the-other papers in the row or stack on the delivery belt-and so designate or mark a group containing apredetermined numberof newspapers, the number being dependent on the time relation of thefiipper finger to the rotary delivering fly.

The present invention is directed to nicely adjusting the flipper, whetheror notthe number of-newspapers in the designated group is varied. The invention is also directed to changing the relation between flipper finger and the rotary fly so that-the number of papers in the designated groupma-y, if desired, be varied, and especially to thus vary the designated number in a relatively small de gree, assay from twenty-five 'to twenty-six papers. The reference to a rotary fly and other details of the usual form of delivery must not be construed as limiting the invention, as it could be applied to other forms of delivery mechanism.

In connection with the foregoing, rectifyingmeansare provided for maintaining to a nicetv, or recovering, the proper relation between the folder fly and the actuating cam, or equivalent actuating mechanism for the flipper finger. This nicety of ad ustment 1s obtained whether or not the designating or marking mechanism is varied to change the count of the newspapers. Vhen the gear drive is changed to effect the change in the number of papers in the group, the rectifying means will also insure proper relation between the folder fly and the actuating cam for the flipper finger as to secure the proper countor designation in conjunction with making the desired changes in counting mechanism ()ther f .tltlllCS and obj ects of the invention will be first set forth in connection with the appended detailed description of the present preferred embodiment and it will be un derstood that the foregoing general description and the following detailed description of the invention are illustrative and exemplary but are not restrictive of the invention.

Referring now to the embodiment of the invention, illustrated by way of example in the accompanying drawings and referring primarily to certain of the folding and delivery devices of a rotary printing press (Fig. 5), the rollers 1 and E2 of the transverse folder, which makes the final cross fold in the newspaper, are journaled in the frame '3. A rotary fly 4 has its shaft 5 journaled in the frame 3, and is provided with a plurality of arms 6. between which are the spaces 7 into which the completed newspapers are dropped or delivered from the folding rollers 1 and 2.

The rotary fly 4 lays the completed papers upon asuitable delivery device, such as a traveling belt 8, running over a roller 9, and having supporting and tensioning rollers 10 and 11 carried, respectively, by arms 12 and 13. fixed to a shaft 14, journaled in the machine frame.

The finished papers are laid upon the belt 8 in a row or series uniformly spaced or disposed, and for the purpose of indicating, designatmg or marking groups containing a given number of papers, it is customary to periodically displace a paper in the series or rows upon the belt 8, the device effecting this operation after the delivery of the predetermined number of papers. Thus, each projecting paper will mark a group with a given number of papers therein between it and the next projecting paper. Thus the papers may be picked up and handle in exact numbers without countin In the mechanism for effecting this, a. flip per arm 15 is adapted to operate periodical- 1y upon a folded paper in the rotary fly and give it a slight forward push or rather prevent its coming back in the fly as far as it otherwise would, just as it is delivered, for the purpose above described. The flipper arm 15 is fixed on an arm 16, which is fixed to a shaft 17, journaled in the machine frame 3. Fixed to shaft 17 is an arm 18, in the end of which is journaled a cam roller 19, cooperating with acam 20.

The mechanism so far described is of a usual or standard form, and it will be understood that the present invention may be applied to other forms of newspaper delivery devices than that herein exemplarily shown.

It is desirable to get a nicety of adjustment of the flipper without changing the count of the newspapers in any group.

It is also desirable frequently to change the number of papers in each marked or indicated group of the delivered papers, that is, to have the mechanism displace a newspaper after agiven number have passed, or optionally or selectively, after a different given number of newspapers have passed It is further frequently desirable to vary the operation of the indicating means to change the number in the group relatively very little, for instance, to have the mechanism constructed and operated so as to mark or indicate either a group of t\vent ,'-five newspapers or twenty-six newspapers, although it will be understood that these numbers are merely illustrative.

Accordin ly, means are provided for varying the period of operation of the flipper arm 15, said means being preferably arranged and located between the flipper arm and the drive therefor. For convenience, the detailed description of the present preferred embodiment will begin with the general driving mechanism and will end up at the flipper arm.

A driving gear 34 is fixed upon a shaft 35. journaled in the general frame 3. In the preferred embodiment a change gear, or rpttil change gear mechanism cooperates with the driving gear wheel 34, to change the period of operation of the flipper arm A pinion 36 is shown in mesh with gear wheel 34, this gear wheel being fixed on a shaft 3'7 which is journaled in the end of the arm 38 of a bell crank lever 39, which bell crank lever is loosely pivoted by shaft 40, later to be described. Fixed also to shaft 87 to rotate with the pinion 36 is a pinion 41 which pinion is in mesh with a gear wheel 42 fixed on the shaft '0.

The alternative drive of the change gear, or speed changing gear, comprises a pinion 43, fixed to a shaft 44, and a pinion 45 is also fixed to shaft This shaft is journaled in an arm 46, extending outwardly from the arm 47 of the bell crank lever 39. Pinion 4:) is also in mesh with the gear wheel 42. The bell crank is provided with a handle 50. and with a bolt and slot holding device 51. Thus when the mechanism is in the position of Fig. 1. the drive from gear wheel is through pinions 36 and 41 to the gear wheel 42. \Vhen the bell crank lever is rocked by moving handle 50 to the left, pinion 36 is thrown out of mesh with gear wheel 34. and pinion 4'23 thrown into mesh with the gear wheel 34.

The ratios of the respective pi'nions are such that they will drive the gear wheel 42 at different speeds, so as to eflect the desired difference in the period 'of operation of the flipper arm 15, and of its actuating cam 20 to effect the desired difierence in counting the papers.

As embodied, the further driving connections to the flipper arm actuating cam 20 comprise ineans'f'orrectifying or neutralizing the change'caused in the relative position of the cam 20 and the folder fly 4, by shifting the change gear mechanism. This mechanism operates as stated to rectify the change in position between the cam and fly and thereby to get the proper count in the delivered newspapers.

In the embodied form, this rectifying means is applied to the driving connections to the cam 20 about to be described. Fixed on shaft 40 is a worm 58 (Figs. 2, 3 and l) connected to the shaft by a spline 59, the worm accordingly rotating with the shaft but being slidable thereon. Means are provided for controlling the position of the worm along its shaft, the required movement being relatively very slight, to compensate for an opposite movement, caused by the operation of the change gear mechanism already described.

As embodied, a non-rotating washer 60 on circles the shaft, and abuts on the worm, the outer face 61 thereof being beveled. Abutting on the wedge-like washer 60 is a sliding, bifurcated wedge 62 beveled complementarily with washer 60. The shaft 40 passes througl a central recess in the wedge, and the arms 63 and 64 of the wedge extend horizontally above and below the shaft. On its opposite face the wedge 62 bears against the frame 3.

Means are provided for moving the wedge 62 to and fro accurately and minutely with respect to the shaft 40, and as embodied, screw shaft 68 is journaled in a bracket 69, carried upon the frame. The shaft has a hand wheel 70 at the exterior end thereof, with its hub abutting on the bracket 69, and with a positioning collar 71 fixed thereto on the other side of the hub, whereby the rod is rotatable in the journal bracket 69 but is held against longitudinal movement. At its other end, rod 68 is provided with a screw-thread 72, which is threaded into the tapped projection 78 of the wedge 62.

Thus as the hand wheel 7 0 is rotated, the wedge 62 is moved finely and accurately to and fro to correspondingly move the worm 58 along the shaft 40, thereby effecting a slight compensating or correctional relation between the worm and its worm wheel 80, later to be described. A helical spring is in compression between the hub of the worm 58 and a collar 76, fixed on the shaft 40, and this spring yieldingly presses the worm against the washer 60.

cry of the circular flange 100.-

tion 114, with thecam 20 Meshing with the worm 58 is a worm wheel 80, fixed on a shaft 81, which shaft is journaled in abearing 82, carried on a bracket 83 supported by the machine frame, the hub of the worm wheel abutting against one end of the bearing 82. A beveled gear wheel 85 is fixed to the other end of shaft 81, and has its hub abutting on the opposite end of the bearing-82.

Meshing with the beveled gear 85 is a beveled gear 86 rotatably mounted on a shaft 87 journaled in a sup iorting bearing and standard 88., fixed to the machine frame. Fixed to bevel gear 86 to rotate therewith is a gear wheel 92, which meshes with a gear wheel 93, rotatably carried on a shaft 9%. Gear wheel 93 has its hub 95 integral with or fixed to the hub 96 of a part or member of the flipper arm actuating cam 20.

Thus when the hand wheel 7 0 is turned to move the adjusting orposition-varying or controlling wedge 62, the worm moved longitudinally along its shaft l0, and by means of its movement it is possible to adjust the cam disc 20 to exact position.

Means are likewise provided for correspondingly setting the flipper finger or kicker and this is a very precise and delicate operation. In the embodied form of means for effecting this, the hub 96 of the cam 20 is keyed to the shaft 94, the hub carrying a circular flange 100. The cam 20 proper is circularly centrally recessed so that it will rest and also rotate upon the periph- The flange 100 and the cam 20 are connected together to be angularly or circularly relatively positionable by suitable means, such as bolt and slot connections 102 passing through a slot in one and screwed into the other, and'which may be of usual form.

In the embodied form of means for angularly positioning the rim 20 en ti 0 central part 100, as-above referred to, there is rotatably mounteo in the cam 20 a short shaft 106, to'which is fixed a hand-wheel 107, on

one face of the cam. Fixed also on shaft 106, and nested on the opposite face of the cam in alinement with the flange 100 is a pinion 108. Afew gear teeth 109 are formed in the peripheral edge of the cicular flange 100. By rotating the hand wheel 10?, which is friction-tight, a very nice and precise positioning of the cam 20 with respect to its supporting hub 94 and the train of driving mechanism is secured.

The cam 20 is provided with one or more depressions 110, with which the roller actuate the kicker arm or flipper 15. If desired, a silencing plate 112 may be provided forthe depression 111, and thereby the number of designated papers may be doubled. The plate 112 is pivotally supported at 1l3 and has an arcuate bolt and slot connecwhereby it may be held in either the operative or inoperative position.

It will be clear from the foregoing that the resultant displacement of the flipper, due to changing the count of the newspapers in any group, may be corrected or compensated by sliding the worm gear 58 along its shaft by actuating the wedge 62 through the hand wheel and cooperating screw-threads. ()r, the same correction or compensation can be secured by adjusting the cam 20 upon the l'nember 100. In the latter case, the worm gear adjustment would not be necessary.

It will be further noted that the adjustment of the worm gear 58 can be made while the press is running. This is also true in those cases where itis desired to make the adjustment simply by means of the adjustable cam, for the cam moves so slowly that the parts can be readily adjusted while the press is in motion. It will also be noted from the foregoing description that the flipper adjustment can be made by the adjustable cam simply to insure a nicety of adjustment of the flipper, without any dependence whatever on or connection with the counting mechanism controlling the number of newspapers in the groups. 01', the sliding worm gear 58 controlled by the wedge 62 could be used for the same purpose, even if gears are not used to change the count.

\Vhen the gears are used to chan e the count, the position of the flipper is adjusted or rectified by either the sliding worm 58 and its operating connections, or by the ad jnstable cam 20. Either mechanism is suflicient to make the adjustment. Such an adjustment or rectification is necessitated by the fact that when the gears 36, 43 are shifted to change the count, shaft 40 is angularly shifted, which angular shift would be transmitted through gears 80, S5, 86, etc. to cam 20 and would introduce an error in the count, unless compensated for by either of the two described rectifying or adjusting devices.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
